I am not sure where you get the idea that the 'ruling class' delegated this decision, or that the free market decided anything at all. Historically, the 'ruling classes' don't tend to share power, and have made plenty of consequential environmental decisions with no market feedback (see Mao's Four Pests campaign). The free market on the other hand is just a mechanism for pricing and exchange, it doesn't decide anything; individual market actors make decisions, and spontaneous order results.
I'm even more confused about how you got from the biome to the stock market and NFTs; perhaps you could enlighten me? NFTs seem to be a bubble, but they're not as wasteful as proof of work tokens.
